Go to https://access.redhat.com/documentat...terprise-linux, click on product version 6, then read the Migration Planning Guide. Or direct link to the guide (not sure if it works): https://access.redhat.com/documentat...ide/index.html.

In this case, either get support or switch to Centos, which is a clone of Red Hat.

Some time ago, I converted my unsupported RHEL 6 system to Centos 6, but I don't have the instructions anymore. They are on the web.
Perhaps you can directly update from Red Hat 5 to Centos 6. Again, ask the internet.

Thanks berndbausch,

Other wise Did you have any idea which file systems have to take backup

Take a full backup so that you can easily go back in case your applications don't work with RHEL/Centos 6.
